What is a grade calculator?
A grade calculator converts points earned into a percentage and, when a grading scale is available, a letter grade. A test grade calculator can help you understand a quiz or exam result, while a percentage grade calculator can show how much of the available credit you received.
The calculation is straightforward: divide points earned by points possible, then multiply by 100. Points possible means the total available for the assignment. The result tells you what share of that total you earned. A letter grade is a separate interpretation of the percentage, and grading scales can differ between schools and classes.
Why your grade matters
A percentage gives you more detail than a letter alone. It can help you spot how much credit you earned and how many points you missed. That makes it easier to review an exam, identify topics that need more work, and decide how to prepare for the next assignment.
A test score is not always the same as your overall course grade. Classes may use weighted categories, participation, projects, or other assignments. Use this calculator for a points-based result, then check your syllabus or ask your instructor how that result affects your course grade.
How to use this grade calculator
- Enter the points you earned on the assignment.
- Enter the total points possible. Check the assignment or grading portal if you are unsure.
- Calculate the result. The calculator divides your earned points by the possible points and multiplies by 100.
- Review the percentage, letter grade, and points missed. Compare the letter grade with your class grading scale if you need to confirm how it was assigned.
Grade calculator example
Worked example
If you earned 43 points out of 50 possible, divide 43 by 50 and multiply by 100. The result is 86% (B). You missed 7 points. The percentage follows the formula, and the letter grade shown is the sample result; check your class scale because letter-grade cutoffs can vary.
How to read your grade calculator result
Points earned and points possible are the inputs. Percentage is the share of available points you received. Letter grade translates that percentage into a school’s grade label, while points missed is the difference between the possible points and the points earned.
Use the percentage to review your performance on that assignment. Do not assume it is your final course grade unless the class calculates the course grade using only those points. If the result seems inconsistent with your report card, check whether the assignment has a different weight or whether your school uses another grading scale.
How to improve your test grade
- 01
Review the points you missed
Look at each missed question and sort errors by topic. Practice the concepts you misunderstood, and ask your instructor to explain an answer when the reason for losing credit is unclear.
- 02
Check the grading rules
Read the syllabus or assignment instructions for the grading scale, partial credit, and any retake or correction options. Ask your instructor what work can still affect your course grade.
- 03
Prepare around the next assessment
Use the missed-question review to guide your study plan. Spend more time on weak topics and practice the kinds of problems or questions that challenged you.
Common grade calculator mistakes
Entering the wrong total
Use the points possible for that specific assignment, not the total points for the course. If the assignment includes bonus points or partial credit, follow the way your instructor records them.
Treating the letter grade as universal
Schools and instructors may use different percentage cutoffs. Confirm the grading scale for your class rather than assuming a letter grade means the same thing everywhere.
Confusing an assignment score with a course grade
A points-based result covers the work entered into the calculator. It may not account for category weights, other assignments, or course policies.
The grade formula
Grade = points earned / points possible x 100.
Key terms
- Percentage grade
- Points earned divided by points possible, multiplied by 100.
- Points possible

- Letter grade

Grade questions
Can the same percentage have a different letter grade?
Yes. Letter-grade cutoffs vary by school, class, or instructor. Check the grading scale that applies to your assignment.
Does this calculator show my overall course grade?
It calculates a result from points earned and points possible. It does not account for course weighting or other assignments unless those are included in the inputs.
What does points missed mean?
Points missed is the difference between the assignment’s possible points and the points you earned.
